Keeping case for the cassette tape and others

Abstract

A keeping case for a cassette is provided. The keeping case includes an inner case pivotally connected to an outer case by a point hinge. Connecting bodies are provided for connecting one such keeping case to another keeping case adjacent thereto. The connected keeping cases are able to stand freely and to enable access to cassettes stored therein.

What is claimed is: 
     
       1. A keeping case for keeping a generally planar article, comprising: an outer case having spaced apart parallel first and second side walls and a plurality of end walls connected to and extending between the side walls, the end walls having a plurality of connecting recesses therein extending between the side walls, each said connecting recess including opposed first and second edge walls extending between the side walls, the first edge wall of each said recess having an undercut extending from the first side wall to the second side wall, the second edge wall of each said recess having an undercut terminating intermediate the side walls to define a step in said recess;   an inner case dimensioned to receive the planar article therein and being dimensioned to be at least partly received within the outer case;   pivoting means connecting the inner and outer cases for enabling rotation of the inner case relative to the outer case in the plane of the article in the inner case; and   a connecting body for each of said connecting recesses, each said connecting body being substantially planar with opposed top and bottom surfaces, opposed first and second sides and opposed first and second ends, each said connecting body being slidably engaged in one said connecting recess, the first side of each said connecting body defining a rail slidably engaged in the undercut of the first edge wall of the respective connecting recess, the second side of each said connecting body defining a prominance adjacent the first end and engaged in the under cut of the second edge wall of the respective connecting recess, each said connecting body defining a length between the opposed first and second ends thereof approximately equal to the spacing between the first and second side walls of the outer case, each said connecting body being disposed in the respective connecting recess such that in a first portion the ends of the connecting body are aligned with the respective side walls, and such that in a second position the first end of the connecting body is disposed intermediate the first and second side walls of the outer case with the prominence engaging the step, and such that the second end thereof projects beyond the second side wall of the outer case, the top surface of each said connecting body having ribs extending between the first and second sides thereof for facilitating slidable advancement of each said connecting body in the respective connecting recess between the first and second positions, each said connecting body enabling connection of the keeping case to another substantially identical keeping case, such that the respective planar articles therein are disposed in substantially parallel side-by-side relationship to one another.   
     
     
       2. A keeping case as set forth in claim 1 wherein, the inner case comprises a locking member movable fixed to the inner case by means of a spring for urging the locking member away from the inner case, and the inner case has an opening opposed to the locking member to enable the locking member to pass through the inner case and engage the planar article therein.
